I want to know that is that teh > way its working . If there is a stunnel instance on the client machine accepting connections on port 80 and connecting to the web server at the https port (default or not), a user could specify `http://localhost' to connect to the web server (and the traffic between the client machine and the server would be secured). > And is it possible to implement the same in a live enviroment ,in > which teh webserver will run on different port ,but users dont need > to specify the port number . Yes. As soon as the destination port for the 'first hop' of a redirected/tunneled connection is the default port for the protocol in question, there is no need to specify the port number. The port numbers of 'intermediate hops' are configuration options for the two stunnel instances (in this case), so the user dosn't have to care about them.

Help on configuring Stunnel
by Patel Dippen-CDP054 24 Jul '08

24 Jul '08

I downloaded the pre-compiled Windows version of Stunnel (stunnel-4.25-installer.exe). We need to deploy this on 2 machines A and B. The way it works is: - B connects to A - then A connects to B How should I configure Stunnel on machine A, since, in the first case A is the Server and in the 2nd scenario A becomes the Client. Questions on deploying Stunnel on machine A: - Can I run just 1 instance of Stunnel on machine A? It seems I cannot since I have to set the "client = yes" in the 2nd scenario - Do I need to run multiple instances, 1 running as the Server and the 2nd as the Client? Here is the config file I used on the machine A: **************************** cert = stunnel.pem socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 [iPerfS] accept = 5010 connect = 127.0.0.1:5001 [iPerfS] accept = 5002 connect = 12.50.0.25:5020 **************************** Here is the config file I used on the machine B: **************************** cert = stunnel.pem socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 [iPerfC] accept = 5001 connect = 12.50.0.26:5010 [iPerfS] accept = 5020 connect = 127.0.0.1:5002 **************************** Regards, Dippen

Stunnel 4.24 patch to allow stunnel to search for the OCSP responder within an X.509 certificate's AIA extension.
by Bruce Keats 24 Jul '08

24 Jul '08

Hi all, This patch also fixes a problem with stunnel accepting an "unknown" response as "good" and allows the connection to be setup. An OCSP responder can return one of three responses (good, revoked, unknown), however the code would accept "unknown" as good. This patch fixes that problem and treats an "unknown" response as a failure. Stunnel can query an OCSP responder to determine the revocation status of a certificate when stunnel is verifying the certificate. The code works great, however it is uses a preconfigured OCSP responder. The OCSP responder's IP/hostname is specified in the stunnel configuration file as a URI. I found this rather restrictive, so I added code to extract the OCSP responder's URI from the certificate. As per RFC 3280, one of the valid extensions for X.509 certificate is the Authority Information Access (AIA) where the "accessMethod" can be "is-ad-ocsp" to identify the OCSP responders location as per RFC2560. There can be more than one OCSP responder listed in the AIA because it is a sequence. Each location is queried in the order they appear within the certificate until either a "good" or "revoked" response is received. If an "known" response or a failure then the next OCSP responder is checked. If all OCSP responder queries result in failure then the validation also fails.. A new configuration option "OCSPaia" was added. If the "OCSPaia=yes" then the stunnel will look for the OCSP responder(s) within the certificate's AIA. The locally configured "OCSP=<url>" overrides the OCSPaia option. Bruce

Wrong documentation
by Sandeep Kumar 23 Jul '08

23 Jul '08

Look at this page http://www.stunnel.org/faq/stunnel.html#configuration_file In service level options section, under the explanation of "CRLpath" it is said that all files in it should be of the form XXXXXXXX.0. But my stunnnel setup worked only when i names as XXXXXXXX.r0 instead of XXXXXXXX.0. -- Sandeep Kumar http://students.iiit.ac.in/~sandeep_kr

Thanks for reply. Yesterday, I have tried to compile stunnel with Sun Studio. It got problem linking with libwrap, so I turned off libwrap support. And it compile (without knowing there is a libwrap patch) and there is only one single running stunnel process. Regards Patrick

Hi I use this to compile stunnel: The gcc and openssl is from Solaris SFW. # export CC=/usr/sfw/bin/gcc # ./configure --with-threads=pthread --with-ssl=/usr/sfw --localstatedir=/var After installing and starting stunnel, I found there are mutiple stunnel processes. There is a PID file which store one of the stunnel process. I have tried to kill that PID, stunnel is bring down. But there other stunnel processes running. Any ideas? Regards Patrick

Config Sanity Check
by Caplan, Michael 18 Jul '08

18 Jul '08

Hi There, I am working through an issue with a script that builds a socket connection to stunnel. Stunnel is being used to relay to an Apache web server. I'm building a localhost TCP connection on port 54322, and writing my HTTP data. When reading data back from the socket connection in my script I'm sometimes getting nothing, and other times getting the proper result. I can confirm that the web server is always receiving the request and returning a proper response. Wireshark shows SSL data being transmitted and received, so stunnel is doing its thing. However, the response does not seem to be relayed to my script on the other side of stunnel *sometimes*. My hunch is that I am doing something wrong with my script, but I am hoping that an stunnel guru can rule out any oddities with my stunnel setup. My config is below as well as the output of my log file. Any thoughts? Thanks!
